Eelgrass restoration Sweden - Kosterhavet National Park

Eelgrass has been declining in the Swedish West coast since the 80's and there is an increasing interest to stop this decline and restore the bays that were lost. The Zorro group at Gothenburg University is developing and implementing methods for large-scale restoration in Sweden.

In Kosterhavet National Park, eelgrass has vanished in two bays, Tånguden and Långevik. After a drone survey in 2018 where eelgrass was mapped in the park, we found that 16.1 hectares of eelgrass were lost since the 80's. Now, after successful small planting test, we are coordinating a large effort to restore 1 hectare of eelgrass in 2020 and another 1-2 hectares in 2021.
